he System (NH4)2SO4-NH4NO3-NH4SO3NH2-H2O at 25°C

H2O at the Phoenix landing site.

The Phoenix mission investigated patterned ground and weather in the northern arctic region of Mars for 5 months starting 25 May 2008 (solar longitude between 76.5 degrees and 148 degrees ). A shallow ice table was uncovered by the robotic arm in the center and edge of a nearby polygon at depths of 5 to 18 centimeters. In late summer, snowfall and frost blanketed the surface at night; H(2)O ice...

The solubility of fluorite in H2O and H2O–NaCl at high pressure and temperature

The solubility of fluorite in H2O and H2O–NaCl has been measured at 600–1000 °C, 0.5–2.0 GPa in a piston–cylinder apparatus. Fluorite dissolves congruently at all conditions investigated. The data indicate that the concentration of fluorite dissolved in H2O is low at 600 °C and 0.5 GPa (0.0014 mol/kg H2O) but increases strongly with temperature (T) and pressure (P) to 0.247 mol/kg H2O at 1000 °...

Rotational quenching of H2O by He: mixed quantum/classical theory and comparison with quantum results.

The mixed quantum/classical theory (MQCT) formulated in the space-fixed reference frame is used to compute quenching cross sections of several rotationally excited states of water molecule by impact of He atom in a broad range of collision energies, and is tested against the full-quantum calculations on the same potential energy surface. In current implementation of MQCT method, there are two m...

Lithium diaqua­magnesium catena-borodiphosphate(V) monohydrate, LiMg(H2O)2[BP2O8]·H2O, at 173 K

The crystal structure of LiMg(H(2)O)(2)[BP(2)O(8)]·H(2)O consists of tubular structural units, built from tetra-hedral (∞) (1){[BP(2)O(8)](3-)} borophosphate ribbons and (LiO(4))(n) helices running along [001], which are inter-connected by MgO(4)(H(2)O)(2) octa-hedra, forming a three-dimensional network structure with one-dimensional channels along [001] in which the water mol-ecules are locate...
